Our old and trusted ordering system (developed in 2012) was showing its age. Since the original application had no automatic tests, a complete rewrite was done.
## Example:
Decisions and goals in this project:
```python
- make a "classical" web app with a little bit Javascript sprinkled in
- [Python](https://www.python.org) as main programming language
import ordr3
- [SQLite](https://duckduckgo.com/) as database backend
- [Pyramid](https://trypyramid.com) as web framework
ordr3.run()
- leverage the design principles shown in [Cosmic Python](https://github.com/cosmicpython/book/blob/master/Readme.md)
```
- have automatic unit test and functional tests, the coverage should be above 90%
- complete data migration from the old system
This new system is now online at https://ordr.cpi.imtek.uni-freiburg.de since late April 2020
